Although Malaysia’s position on the path of development and its role as an emerging Asian power are now widely recognized, the country’s promotion of Asia as an alternative to the Western interpretation of the international order, together with its positioning within the Islamic world, has made Malaysia’s transition from a crisis of rationality to strategic rationality an important subject of analysis. This article examines the role of Mahathir Mohamad’s leadership in Malaysia’s development trajectory and seeks to explain this process by conceptualizing the strategic rationality of leadership. Accordingly, the study addresses the following question: What role did Mahathir Mohamad’s leadership play in Malaysia’s transition from a crisis of rationality to strategic rationality? The study hypothesizes that Malaysia’s development over the past several decades has been driven by the strategic rationality of Mahathir’s leadership, characterized by such indicators as bounded rationality, political tragic thinking, trust-building, internationalization, issue prioritization, adherence to the rule of law, opposition to corruption, reliance on reality as a guide for policymaking, pragmatism, and future-oriented retrospection. Methodologically, the study employs a descriptive and content analysis of works related to Mahathir Mohamad, drawing on library-based sources and adopting an interpretive approach.
